Abstract

Wind power is one of the most promising renewable resources and Doubly Fed Induction Generator (DFIG) is considered the most cost effective generator for connecting wind power to the grid as it has advantages over other types of wind generators such as operating under variable wind speeds, moderate size of power electronics, and complete control of active and reactive power. But it has consequences on the performance of power system especially power system stability. This paper states the influence of DFIG location on small signal stability using Eigenvalue analysis. Then, Evaluating PV Curve of critical bus as an indicator to state the impact of integrating wind power through DFIG on the voltage stability of power system under different Penetration levels. Besides approving the optimal Mvar for each penetration level to operate the system with wind power in a stable way using trial and error method. The proposed simulation is tested on IEEE 39 bus test system using DIgSILENT PowerFactory software with five penetration levels of DFIG to examine: 4%, 12%, 21%, 31% and 41%.
